A boil water advisory has been issued in LaSalle and Lachine. It will most likely will not be gone until Tuesday at the earliest.
Once the samples of water from both of these boroughs have been inspected, action will be taken.
City officials say that this problem is because of water treatment chemicals being used incorrectly at a treatment plant in LaSalle on Sunday.
Roughly 80, 000 people are affected by this advisory. This includes homes south of St. Patick, west of Dollard Avenue, as far south as 80th Avenue and east of Dollard Ave to Lapierre Street. The north of Newman Boulevard is also included in this warning.
